Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to an underground tunnel drainage device. Background Art

[0002] Tunnel drainage is a key component to ensure the safety and efficient operation of underground tunnels, especially in rainy or groundwater-rich areas. The main purpose of the tunnel drainage system is to prevent water from threatening the safety of the tunnel structure, ensure that the tunnel is dry, and ensure the safety and comfort of driving. There are drainage ditches or pipes in the tunnel to collect water in the tunnel. Regularly check the status of drainage pumps, drainage ditches, drainage pipes and control systems, clean up debris in time, and ensure that the drainage system is always in good working condition. Correct drainage design and management can prevent tunnel collapse or other safety accidents caused by water damage;

[0003] The Chinese patent authorization announcement number is CN219774188U, and the name is a tunnel drainage device, including a device body; a water pump is arranged at the bottom of the device body, the water pump is connected with the inside of the device body, and a filtering mechanism is arranged on the side wall of the device body; the utility model realizes the function of the motor driving the scraper to move at the top of the water flow hole through the structural design of the filtering mechanism, cleaning the gravel at the top of the water flow hole, allowing the water to flow into the water storage tank faster from the water flow hole, and finally discharged from the water outlet, which solves the problem that the existing tunnel drainage device water pump takes in the tunnel water through the water inlet pipe and then discharges the water from the water outlet pipe. Due to the large amount of gravel inside the tunnel, the gravel is easy to block the water outlet pipe during the water discharge process, reducing the pumping efficiency and delaying the construction time, thereby improving the efficiency of drainage work;

[0004] The shortcomings of the above scheme are: although the above scheme can improve the drainage efficiency, when draining water, only the gravel is filtered, but the smaller particles, such as sand and silt, accumulate into clumps and block the drainage system. Only filtering the gravel may not effectively prevent the suspended particles in the water from settling in the drainage system. In addition, when draining water, the particles in the sewage may settle in the pipes, resulting in increased water flow resistance. The pump needs to provide greater power to overcome these resistances, thereby increasing energy consumption. Utility Model Content
